two questions, please help.

Dear teachers,
please read the following two questions.
1.
For example, somebody good at working with his hands and figuring out how machines function might find a responsible position in a science lab or working backstage in a theater.

this paragraph is extracted from one article, I don't understand why "working" is not "work", I think it should be "work", which has the same function as " find".

2.
As children mature, the assessments would continue in a different vein.

what does "in a different vein" mean?


thanks a lot.

1. For example, somebody good at working with his hands and figuring out how machines function might find a responsible position in a science lab or working backstage in a theater.
this paragraph is extracted from one article, I don't understand why "working" is not "work", I think it should be "work", which has the same function as "find".

I believe that "working" is the correct use of the word. I disagree with you that "work" has the same function as the word "find" in this excerpt.
Let's pick apart the passage.....

• This person might find a position working in a theatre.
  "Might" is a modal verb here used in conjunction with the word "find". Therefore, "find" isn't in gerund form.

• This person might find a position working in a theatre.
  "Working" is in gerund form here because it speaks of what one does in the job position.
  
  Other examples:
  I have a position writing for a company.
  He works for a company cleaning office buildings.
  They work as mechanics, fixing cars and repairing damage.
  All of the verbs here are in the gerund form because they describe what work is being done in the position.

2. As children mature, the assessments would continue in a different vein.
what does "in a different vein" mean?

It is difficult to say with certainty what "vein" means here as we don't have the entire context in which it appears. Blindly, I would say that "in a different vein" here means "in a different manner/way/direction".
I hope I've helped you! Let's wait for more opinions.
